 I think the issue is that perl gets built with a newer clang, so it sees
 that `-fstack-protector-strong` works and that fact gets baked into the
 perl configuration files that get installed. Then it tries to use this
 flag when building perl modules, even if the perl module is built with an
 older compiler that doesn't understand that flag.

 Josh tried to address some of this problem in
 [f35a2c53331234cc730b090b1b866d4b1702a747/macports-ports] but it only
 covered specific flags, and didn't include this one. I'm not sure what the
 right solution is, other than explaining to the perl developers yet again
 the folly of their assumption that the compiler that's used to compile
 perl will be the same compiler used to compile all modules.
